Several guitarists and bassists use it to simulate a 12-string guitar texture or add extra octave layers, and one bassist says it makes a 4-string sound like an 8 or 12-string.

music_noteExcellent for solo bassists and duosexpand_more0 mentions
Bass players in lead-vocal/bass duos use the MO-2 as an octave-up or thickening tool to fill out the sound like a POG, letting them sound huge without a guitarist in the band.

check_circleGood always-on thickening toolexpand_more0 mentions
With tone rolled off and detune set to a subtle octave-down, users find it works as a low-key, always-on thickener that tracks single notes and chords fine in that specific setting.

On instruments like electric mandolin, the mode switch behaves predictably, giving octave-above, octave-above-plus-unison, or full three-layer spreads to broaden range.
